[0031] like Figure 1-5The antenna network card shown in the figure includes a network card 100 and an antenna 200; the network card 100 includes an upper shell 101, a lower shell 102 and a circuit board 103, the upper shell 101 is provided with a first groove 1011, the lower shell 102 is provided with a second groove 1021 corresponding to the first groove 1011, the first groove 1011 and the second groove 1021 cooperate to form a limiting groove, the circuit board 103 is arranged in a shell composed of the upper shell 101 and the lower shell 102, the side wall of the shell is provided with a through hole, the through hole is connected to the limiting groove, and the second groove 102 A limiting plate 1022 is provided, and the limiting plate 1022 is arranged along the length direction of the second slot 1021; the antenna 200 is electrically connected to the circuit board 103, a rotating shaft 201 is provided at one end of the antenna 200, a limiting disk 202 is provided at the end of the rotating shaft 201, a limiting block 203 is provided at one end of the rotating shaft 201 close to the limiting disk 202, the rotating shaft 201 extends into the limiting slot through a through hole, and the limiting disk 202 is located in the limiting slot; when the antenna 200 rotates to the limit position, the limiting block 203 conflicts with the limiting plate 1022. It should be noted that the limiting plate 1022 divides the second groove 1021 into a left groove close to the side wall of the lower shell 102 and a right groove away from the side wall of the lower shell 102. The limiting plate 202 is located in the right groove, so that the two side surfaces of the limiting plate 202 respectively contact the limiting plate 1022 and the inner side surface of the right groove, thereby increasing the contact area between the limiting plate 202 and the limiting groove, thereby increasing the friction between the limiting plate 202 and the shell, so that the antenna 200 will not shake during assembly, which is beneficial to improving the assembly efficiency of the antenna 200, and, The setting of the limit plate 1022 will also hinder the limit block 203, so that the limit block 203 can only rotate within the first groove 1011, avoiding the antenna 200 from rotating 360°, making the connection between the antenna 200 and the network card 100 more stable, which is beneficial to improving the service life of the antenna 200. In addition, the limit plate 1022 has a semicircular hole for the rotation shaft 201 to pass through, so that the rotation shaft 201 contacts the top surface of the limit plate 1022, further improving the stability of the rotation of the antenna 200.

The strip-shaped grooves 204 are provided on the center line of the outer surface of the limiting plate 202, and the plurality of strip-shaped grooves 204 are evenly spaced, and the strip-shaped protrusion 1023 extends into the strip-shaped groove 204. It is easy to understand that when the antenna 200 is rotating, the strip-shaped protrusion 1023 cooperates with the strip-shaped groove 204 to achieve the effect of rotating the gear and give the user a sense of damping, so that the user needs to use a certain amount of force to rotate the antenna 200, which is conducive to improving the user experience. In addition, the strip-shaped protrusion 1023 cooperates with the strip-shaped groove 204 to prevent the antenna 200 from rotating unexpectedly, thereby improving the stability of the antenna 200.

[0033] Please refer to Figure 1 In a possible implementation, there are two antennas 200, and the two antennas 200 are respectively disposed on opposite side walls of the network card 100.

[0034] Please refer to Figure 3 In a possible implementation, a avoiding groove 1012 for avoiding the stop block 203 is provided at the top of the second groove 1021. It is easy to understand that the stop block 203 rotates in the second groove 1021, the stop block 203 is in a rectangular shape, and the top surface of the second groove 1021 is a plane. When the stop block 203 rotates to the center of the second groove 1021, the stop block 203 will collide with the top surface of the second groove 1021. Therefore, the setting of the avoiding groove 1012 can avoid this problem, so that the stop block 203 can slide smoothly.

[0035] Please refer to Figure 3 and Figure 4 In a possible implementation manner, a buckle portion 1013 is provided on the upper shell 101 , and an elastic buckle 1024 is provided on the lower shell 102 .

[0038] Please refer to Figure 2 In a possible implementation, the circuit board 103 is provided with a communication interface 1031, and the communication interface 1031 extends out of the housing. It is easy to understand that the housing is provided with a through hole for the communication interface 1031 to extend out, and the communication interface 1031 is a USB interface. The network card 100 is connected to other devices through the USB interface. In other embodiments, the communication interface 1031 may also be a Type-C interface.

[0039] Please refer to Figure 2 In a possible implementation, the circuit board 103 is further provided with an indicator light 1032, and the indicator light 1032 extends out of the housing. It is easy to understand that a strip-shaped through hole is provided on the top surface of the upper housing 101, and the indicator light 1032 extends into the strip-shaped through hole, so that the user can easily observe the indicator light 1032.
